This tutorial provides an introduction to the elementary concepts of programming with ProXT. It incorporates some instruction on the basic ideas behind the X Toolkit (Xt) and the Motif widget set. However, this is not a comprehensive tutorial on Motif and Xt programming. For such refer to The X Window System: Programming and Applications with Xt, OSF/Motif Edition (Douglas Young, Prentice-Hall). Programmers who are already familiar with Motif will find this tutorial useful in translating their knowledge to ProXT. In addition the original Motif and Xt naming conventions are preserved to a great extent, which is intended to facilitate the transition to ProXT.
